B) If it were an octopus, I’d say revenge. But as it was a squid, probably just stupidly messing around. Now, a cuttlefish… first small steps toward world domination. And might be pulling the strings behind those easily manipulated squid…

I suspect shenanigans. I thought squid actually had very tiny gullets, much smaller than their beaks, and so they must rip out tiny bits of flesh to swallow them. I do not see how even a largish squid, as this was, could swallow a 3 lb bomb.
